As you will have gathered from previous correspondence, I am trying to find a suitable paint product to decorate the internal walls of an old chapel which due to a multitude of sins by previous owners, currently has a “mixed bag” of finishes including its original lime/lath plaster, modern gypsum plaster (skimmed over areas of old lath lime plaster, new lime and horsehair plaster recently applied to solid brick columns and existing emulsion paint, the latter covering the majority of surfaces and probably applied about five years ago.
I have ruled out using limewash as I understand this won’t adhere to the existing emulsion and I’ve also kicked the idea of modern breathable resin and isoparafin paints into touch for the time being. I’m therefore down to either Distemper or Breathable emulsions. (I need the breathability for the areas of new lime plaster).
The distemper sounds interesting as I understand it has an aesthetically appropriate finish and getting things to look authentic is important to me, however I need to know a bit more about this product before making my decision.
The internal height of the building makes it difficult to decorate (scaffolding etc) and once it is decorated, it may from time to time be full of people, so it’s important that I take into consideration practicality as well as authenticity.
Any advice you can give on the following would be appreciated.
1.I understand you can get Oil bound or Casein bound distempers and some with an additional additive of gelatin glue. Which of these would be the most suitable for my application and are they all equally breathable?
2 Does distemper adhere to emulsion painted surfaces?
3. Do I need a primer or undercoat?
4. How many coats are generally required to obtain a consistent colour on differing surfaces, and what is the approximate sq meter coverage for say five or ten litres?
5. How long dose distemper stay wet during application i.e. in order to maintain the wet edge? I understand that this is important so as not to leave dry line marks or a patchy finish.
6. What’s the preferred application method brush or roller?
7. How long does it last in the tub or container before going off?
8. Would there be any chance of it rubbing off onto peoples clothes?(oil bound or otherwise) I have original built-in bench pews along the walls and so people’s shoulders may touch or rub against the wall.
9. If a distemper painted area becomes scuffed or stained can it be cleaned or do you have to repaint over the mark? If the latter does it blend in quite easily or would you have to paint the whole wall to avoid the non patchy finish (the wet edge thing again) My problem is that two of the walls require scaffolding to reach the higher levels so repainting the whole wall is not really practical.
10. Does the texture of distemper attract airbourn dirt and dust more easily than breathable emulsion and does it discolour over a period of time requiring regular redecoration? With reference to the scaffolding mentioned above, a low maintenance product would obviously be preferable for me.
